I just went back after 12 years at home, I'm an aide to a learning support teacher in 7th grade. As the others said, don't show any fear around the kids! I received no training whatsoever, so I just figure it out as I go along. I love my job and the kids and actually catch myself thinking on Sunday that I'm ready to get back into class on Monday! Tomorrow is mis-match day, I have to go put together my clashing outfit. Good luck, you'll do great.
